A ventilation measurement device includes a fastening mechanism (8) capable of permanently or detachably fastening the ventilation measurement device (1) to a belt (2) which can be worn around a person's chest. The device includes a substrate (4, 4', 4") coupled to the fastening mechanism (8) and capable of receiving tensional forces transmitted from the flexible belt (2) through the fastening mechanism (8). A strain gauge (3) mounted on said substrate and configured to output a signal with a functional relationship with said tensional forces delivers measurement signals to a controller unit configured to receive and process the signal to produce processed data from the strain gauge signal and to control a transmitter configured to transmit processed data to an external receiver. |
